black_widow87 Posted June 25, 2010 Share Posted June 25, 2010 Hi guys! Iv just had a new single turbo installed as the last one went bang. However both me and my mechanic have been scratching our heads to find out where to plumb a vacuum to the wastegate as the is no vaccum in the turbo itself. Without this plumbed up it will just continue to overboost which is not good Is there anyway we can plumb this into in intake manifold?? Any advice would be much appreciated Quote Link to comment Share on other sites More sharing options...
Rinus Posted June 25, 2010 Share Posted June 25, 2010 A friend of mine got it connected at the back of the intake manifold, next to the idle control valve... Quote Link to comment Share on other sites More sharing options...
supspower Posted June 25, 2010 Share Posted June 25, 2010 Could you not get or make something like this? http://www.atpturbo.com/mm5/merchant.mvc?Screen=PROD&Store_Code=tp&Product_Code=ATP-FTG-010&Category_Code=BCS Quote Link to comment Share on other sites More sharing options...

Iv looked around the idle control valve but there are a few small pipes i dare not tounch, will it be the one coming directly out the back of the throttle body?? Here is a pic of what i can see: Quote Link to comment Share on other sites More sharing options...

Wez Posted June 25, 2010 Share Posted June 25, 2010 man-up and drill and tap into the compressor housing on the turbo! - that what I did If you dont want to tap the housing pretty much any manifold pressure source from the inlet side will do, its just a pressure source.

Homer Posted June 25, 2010 Share Posted June 25, 2010 If you dont want to tap the housing pretty much any manifold pressure source from the inlet side will do, its just a pressure source. Just to follow on from this, it's best practice to have it as close to the compressor as possible (to ensure the solenoid can ract to pressure changes as quickly as possible, hence avoid over boost or surges). It's why nearly everyone taps the compressor. Next best option would be to add a reference on the IC pipe from the compressor. Quote Link to comment Share on other sites More sharing options...
Guest damian Posted June 25, 2010 Share Posted June 25, 2010 manifold pressure source not stable enough for waste gate function..best go for the compressor outlet,, Quote Link to comment Share on other sites More sharing options...

black_widow87 Posted June 26, 2010 Author Share Posted June 26, 2010 Right guys, iv just 'manned-up' tapped into the compressor and fitted the nipple and all is good!! Thanks for your help guys..next time i promise not to be such a girl!! Quote Link to comment Share on other sites More sharing options...
heckler Posted June 26, 2010 Share Posted June 26, 2010 Where does the stock sequential system get its reference from? from the metal vac pipes on top of the sequential system... i believe the wastegate is fed from the compressor on no1 turbo... (dont quote me on that ) Quote Link to comment Share on other sites More sharing options...
Ian C Posted June 26, 2010 Share Posted June 26, 2010 The stock wastegate is plumbed directly into the housing of turbo 1, the pipe is about 5" long Quote Link to comment Share on other sites More sharing options...
